What material is Spandex Yarn made of and what are its characteristics?

The preparation of Spandex Yarn is mainly based on polyurethane, a synthetic polymer. This material has a unique molecular structure and contains amide (urethane) groups. During the manufacturing process of Spandex Yarn, a polyurethane polymer is formed by polymerizing the appropriate monomers. This polyurethane polymer is then transformed into a fiber with exceptional elasticity and resilience, known as Spandex Yarn, through process steps such as spinning and drawing.

The properties of polyurethane give Spandex Yarn its outstanding properties. Its elasticity and resilience make this fiber a uniquely valuable material in the textile industry. Spandex Yarn is widely used to create elastic fabrics with extremely high stretch, excellent comfort and shape retention properties. Whether it's sportswear, underwear, swimwear, etc., they're all popular for their ability to quickly return to their original shape after stretching.

The entire preparation process starts from the polymerization of polyurethane, and by rationally controlling the synthesis conditions and fiber formation process, the final Spandex Yarn is ensured to have excellent quality. This synthetic elastane fiber is favored for its performance in a variety of applications, providing a flexible and efficient material option for textiles.
